I recently came aross a peculiar Problem. When I view a 3 Model of a Character GLB with Morphs with the GLTF viewer from PlayCanvas then everything seems to be working correctly. But when I import an FBX File (Exported from Blender with Shape-Keys, same file but now as FBX) of the Same character with the “convert to GLB” option enabled, morph animations then weirdly affect the lighting of the character. And it does so on every morph Target.
I have recorded a short clip here, where I first load the GLB file with the GLTF viewer (everything works accordingly). Then I open a window which was opened by clicking “Open in Viewer” in the Editor on a Converted (imported as FBX) GLB file in my PlayCanvas Project and get weird results. This does affect one of my applications, where a character then is weirdly lit when playing a morph animation.
Any idea on what I could do here?
I also had an older project with the old animation system and playcanvas-gltf.js and playcanvas-anim.js where I loaded a glb animation and added this as a new animation clip. There everything works properly.
Does this have anything to do with recent updates?
